Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed November 13, 1918. Serial No. 262,355.

To all whom it may concern:

Be it known that I, GOTTLIEB BTDMER, a

citizen of the Republic of Switzerland, res1ding at Zurich,Centralstrasse 53, witzerland, have invented certain new and usefulImprovements in Liquid-Dispensing Apparatus; and I do hereby declare thefollowing to be a clear, full, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same,

ters or figures of reference marked thereon, which form a part of thisspecification.

Thisinvention relates to improvements in liquid dispensing apparatusdelivering a fixed quantity of a beverage upon the insertion of a coin.

The object of the present invention is to provide an' apparatus of theclass referred to which comprises two pivotally mounted levers and amember for controlling the passage of the beverage through a supply pipefor the latter, said levers and mem r being balanced among themselvesand being mechanically connected so that an oscillation of one of saidlevers brought about by an inserted coin effects an opening of Saidcontrolling member and a movement of the second lever from its positionof rest into its operative or working position, the latter beingreturned into its as soon as it falls out of an inclined chute,

efi'ecting thereby a closing of the controlling member of the supplypipe and a returning of the first mentioned pivotally mounted lever intoits position of rest. The controlling member comprises a grid valvehaving slots adapted to be brought into slots provided in a plate fixedto the supply pipe and arranged at rightangles to the axis of thelatter.

- Another object of this invention is to provide a liquid dispensingapparatus having a chute'with a guide-channel for the coins and at leasttwo sections oppositelyinclined relatively to a horizontal lane androvided with an additional guide-channe at the reference being hadto theaccompanying drawings, and to'letof Fig. 1;

position of rest by the coin" register with point of transition of theportion of the guide-channel of an upper section into that of a lowersection, said additional channel being so arranged that the kineticenergy acquired by the coin while it travels through the upper sectionof the chute is again consumed in the additional channel of the lowersection, so that the length of the whole chute may be reduced for a ofthe coin through sai chute.

A further object of this invention is to provide a coin-trap for aliquid dispensing apparatus provided with an inspection hole and withmeans locking an in.- serted coin behind the inspection hole until a newcoin has been inserted into the trap.

This invention'will now be more particularly described with reference tothe accompanying drawings illustrating a constructional example of theinvention.

1ven time of passage arranged a lens in the channel 5 just Referring tothe drawings, 1 denotes the slot for the insertion of the coins into thecoin-trap. The slot 1 forms the inlet end of a forwardly inclinedguide-channel 2 (Fig. 3) provided between an upper rear wall 3 ofsheet-iron and a lower forwardly inclined bottom wall 4. The latter hasan aperture 6, the width ofwhich is smaller than that of a coin adaptedto set the ap paratus into operation, while it is greater than thewidth'of a coin smaller than one of the kind just referred to. 7

forming a vertical continuation of the channel 2 and confined by a rearwall 7 having a bent upper portion, a front wall 9 providedvwith anopening 9 and two side walls 9 In the bent upper portion of the rearwall. 7 are provided a plurality of slots 8 confined by bars 7 10denotes a vertical front wall provided with a slot 11 for the ejectionof too small coins falling through the apertures 6 on a downwardinclined partition wall 12 (Fig. 3). The wall 10 has a further aperture13 behind which is p 14, said aperture 13 being adapted to be used as aninspection opening; To one of the two sidewalls 9 confining-theide-channel 5 is fixed a resilient arm 15 ig. 4) provided vwith a pin 16projecting into the interior of said guidechannel 5 and adapted toarrest a coin 17 behind lens 14. The slots '8 are provided for thepurpose of preventing any influencing of the coin 1.7 arrested in theguide-channel 5.by any object introduced in slot 1,, to displace thecoin,

such object being guided by the bars 9 through one of the slots 8 andthus prevented from coming into contact with the com 17 locked in themiddle portion ofthe channel 5. l

18 denotes adouble armed lever pivotally mounted on a pivot 20 supportedin a board 19 of the apparatus. a The end 18 of this lever l8 isadaptedto act as a coin-holder and is kept in its position of rest beneathprovided the outlet of the guide-channel 5 (Fig. 1). To abolt 21 carriedby the other end of said lever 18 is secured an actuator for thedispensing mechanism, such as a rod or a wire 22 connected at its otherend to a pin 23 on a one armed lever 24 adapted tooscillate about apivot 25 mounted in a spectively.

denotes a vertical member provlded with a guide-channel 5 each ofthefirst mentioned distances is a multiple of the last mentioneddistances re- It will be seen, that the bolt 21 is provided on the lefthand side of the pivot 20 and the pin 23 on the right hand side-of thepivot 25.

Between the two pivotally mounted lever arms 18 and 24 is disposed achute comprising a plurality of sections 27, 28, 29, and 30respectively. In each of the latter is provided an inclinedguide-channel 31 and each of these sections is inclined relatively to ahorizontal plane in the opposite direction with regard to theadjacentupper and lower sections. At the points of transition'of the twoportions of the "guide-channel 31 provided in two meeting sections ofthe chute are provided additional guide-channels 32 and 33, 34 (Fig. 7respectively, each of these addltional channels forming an upwardcontinuation of the portion of the guide-channel31'provided in the lowerone lateral walls 37 and 38 (Figs. 8, 9, 10), the

distance between the latter being such that a small'clearance is leftbetween these walls and a coin rolling down the guide-channel 31. Thebottom of thelatter is formed by a rib 39 and each side wall 37 and 38respectively, is also provided with a rib 40;

To the board 19 is fixed a flanged body ,41

of the dispensing mechanism such as acock connectedto a pipe 42 forsupplying a'beverage. The body portion 41 is provided at v I its frontend with a chamber 43. Within the latter is movably mounted thedispensing element su h as a grid valve 44 into which is screwed the,pin 23 of the pivotally mounted lever 24. The two levers 18 and-.24 andthe grid valve 44 are-balanced" among themselves, by these parts isbalanced in every position that said parts may take. The plate 26already referred to s fixed to the body 41 and constitutes thefront wallof the chamber 43 and is provided'witha pluralityof slot-like apertures45 cor; ponding to the slots 46 of the-grid valve 44. The chamber 43admits a vertical movement of the grid valve- 44, so that the slots .46of the latter may be brought into one row with those of the plate 26,the latter being provided to this end with a slot 47 for the pin 23, so

so thatfthe system constituted that the above mentioned verticalmovement of the grid valve 44 is not prevented by said plate 26. 49denotes an outlet pipe branch for the beverage to be dispensed.

The operation of the hereinbefore described apparatus is as follows:

A coin inserted into the slot 1 passes into the funnel shaped upperportion of the member 7 only when it has the proper size, While a toosmall coin falls through the aperture 6 upon the inclined partition wall12 which guides it to the slot 11 provided in the front wall 10, so thatit is ejected before it causes an actuation of the apparatus. Each'suchactuation of the apparatus is effected only indirectly by a coin of theproper size just inserted, the operation proper being brought by thepreviously inserted coin held behind the lens 14 by the pin 16 of theresilient member 15 until the just insertedcoin causes it to fall towardthe outlet opening of the guide-channel 5. lhe just inserted coincausing the release of the coin 17 is arrested in its turn behind theinspection aperture 13 fitted with the lens 14 by the pin 16. In anapparatus of this kind, any fraudulent tampering is prevented and theinsertion of objects without any value may e discovered at onceby'looking through the inspection aperture 13 and lens 14.

The coin 17 released by the pin 16 falls upon the coin-holder 18 andcauses then, owing to its weight, an oscillation of the pivotallymounted lever 18 in a clockwise direction, it being moved thereby fromits position of rest shown in Fig. 1 in full lines into theworking'position shown in point and dash lines. The Wire 22. connectedto said lever 18 causes in its turn an oscillation of the lever 24 inthe opposite sense, so that it is also moved from its position of restshown in Fig. 1 in full lines into its working position shown in pointand dash lines. Fig. 7 shows both levers 18 and 24 in their work ingposition. Said movement of the lever 24 into its operative position hasthe effect to move the pin 23, and consequently also the grid valve 44,upward, so that the slots 46 of the latter taking up normally theposition shown in Fig. 14 are brought into register with the slots 45 ofthe plate 26 (Fig. 15), the liquid to be dispensed being then able'toflow from the supply pipe 42 into the outlet pipe 49. As soon as thelever 18 has been caused to take up the position shown in Fig. 1 inpoint and dash lines, the coin 17 released by the pin 16 falls into theguide-channel 31 of the chute and rolls at first down hen it reaches thepoint A (Fig. 7), it possesses a certain kinetic energy, the magnitudeof which depends on the weight of the coin and the angle of inclinationof the guide-channel 31. In consequence of the acquired kinetic energy,the coin does not the section 27.

fall vertically into the guide-channel 31 of the section 28 arrangedbelow the section 27, but rolls in the direction of the arrow 0 upwardlyalong the additional guidechannel 32 in which the kineticenergy of thecoin is again consumed. At the point B the coin remains a momentstationary, whereupon the action of gravity causes it to roll at firstdown the additional guide-channel 32 and afterward down the portion ofthe guide-channel 31 provided in the section 28. A similar interruptionof themovement of the coin is also brought about in the additionalguide-channels 33 and 34. It will be understood, that owing to theupward and downward rolling movement carried out by the coin in theadditional guidechannels of the chute, the time taken up for the passageof the whole chute is increased. In other words, for a given time ofpassage of the coin through the chute-on which time depends the quantityof the beverage dispensed-a shorter chute taking up less space can beused when such additional guide-channels are provided. As theinclination of the different sections of the chute influences also thetime of passage referred to, the length of the chute sections will alsocontrol the time of passage of the coin. Owing to the fact that the coinrolling down the chute comes only in contact with the ribs 39 and 40 ofthe sections 27, 28, 29, and 80 of the chute, any arresting of a wet oradhesive coin in the guide-channel 31 due to the adhesion produced isprevented.

The grid valve 44 remains in the position shown in Fig. 15 until thecoin falls through the slot 36 (Fig. 7) of the chute upon the coinholder 27 of the lever 24, which is then caused to oscillate in aclockwise direction, so that it is moved back from the position shown inFig. 1 in point and dash lines into the position of rest shown in thisFig. 1 in full lines. In consequence of said movement carried out by thearm 24, the grid valve 44 is also moved back into the position shown inFig. 14. The coin fails then from the coin holder 27 into the coinreceptacle 50 (Figs. 1 and 2) of the apparatus and the wire 22 connectedto the lovers 18 and 24 In a dispensing apparatus, two pivoted,
